ANTIS'KID MEANS FOR ATOMOBILE To all'whom @may I Be it known that I, VILBERT I. HANDLE,

Va citizen of the United States,residing at Flint Stone, in the count-y of Allegany and State of Maryland, ,have -invented new and useful Improvements in Antiskid Means for'-V Automobile'Wheels, of which the following is a'spe'ciication. f j' Y' The object"of-.my present invention `islftheprovision of simple and highly ellicient antiskid means in ther nature of attachments adapted to be associated with mud chains and `connected inwerking osition with a wheel through the. medium of the mud chain. To the attainment. of the foregoing, vthe invention consists in the improvement as hereinafter describedand definitely claimed,

vIn the'accompanying drawings, forming I part hereof i Figure 1 is a view illustrating the connecltionof two-of my novel attachments together and with Ymud chains; the attachments being shown in plan. v

l, Figure 2 is a v detail-transverse sectionplane indicated'by the llne 2--2' taken in the of Figure 1. l Y

.Figure 3' isa plan view of an auxiliary attachment designed to be employed in conjunction with the attachment shown in Figure il.4 I

Figurefl is a view illustrating the auxiliary attachmentas properly arranged relatively to `an Aattachment of the kind shown in Figure 1.

of modified. attachments constructed in acp Figures 5 and are plan views illustrative cordance with .my invention.

Slmilannumerals of reference designate -corresponding parts in Figures 1 and 2 to fwhich reference will rst be made.

In Figure1,.1 are chains that are designed to extend entirely around a wheel at opposite sides of the tire and felly thereof with a view to holding my novel attachments in working position von the tread of the tire,

' and -22',are lthe attachments of which any I, desired number and size may be employedat intervals aroundthe tread of thel tire. The said attachments are each formed of a single Apiece of appropriate sheet metal, and each is -of cruci-form conguration.- Each fis provided adjacent to the outer ends of its arms 3-With apertures 4, and leach is provided at one side of each arm with a barb flange 5; the saidvbarb flanges being disposed atv rightangles to the body of t e attachments as illustrated.

ployed about the centers of the attachments 2 and 2z of Figuresl and 2 are barbs 2z preferablystruck from the attachments as shown. These barbs 2z manifestly add to the grippingfcapacity of the attachments.

`In Figure 3 I show an auxiliary attachment 2a'. This attachment 2a is apertured adjacent to"`its ends as indicated Vby 41a for fthe connection of chains 6 and is provided `on one ofits long sides with a barb flange 5a', and is also provided-on its oppositelong side with a lateral arm 1.0 on one edge Vof which is a barb flange 5a disposed at ,right angles to the first-named barb flange 5a. As clearly shown in Figure 4 the auxiliary Vattachment is designed to be superimposed upon and employed in conjunction with the attachment 2 of Figure 1; the apertures 4 serving for the connection of-the chains 6.

When the auxiliary attachment iscombined with an attachment 2, `it will be apparentA that the auxiliary attachment will increase the efficiency of the attachment 2 in preventing skidding; also, that the auxiliary attachment bears on the barbs 2Z of the attachment 2. A

In the modification shown in Figure 5, the attachment 2b is provided withl arms 3b, apertured at 4l for the connection of chains, and each arm 3b is provided on one of its edges with a right angle barb flange 5b. The barb flanges 5b are preferably'of truncatedcone shape in outline as illustratedgand are adapted to take secure hold of the surface of a road with a view to precluding skidding.l

The construction of attachment shown in Figure 6 differs from that shown in Figure only in the shape of the arms 5C and the oblique arrangement of the sub-chains 6C.

It will be appreciated from the foregoing that each and all of the disclosed embodiments of my invention are light in Weight7 inexpensive and durable, and at the same time are adapted to efficiently prevent Skidding of an automobile Wheel by Which-they are carried irrespective of the character of the road traversed by the Wheel.

'l'he embodiments herein illustrated and described constitute the best practical ernbodiments of my invention of Which I am cognizant. I would have it understood, however, that in the future practice of the invention various modifications may be made without involving departure from the comprising cruciformplate of metal hav-A ing at corresponding sides of its arms barbflanges, one to each arm, and aisc having apertures for theconnection of means to hold the attachment on a tire; the said barb-flanges on the plate being disposed at anglesto the major portion of the plate, and being blunt and hardened.-

In testimony whereof I aiiix my signature;
